本文从理论上分析区域间有偏技术进步、资本-劳动替代弹性差异对区域政策效果的影响机理。将包含资本和劳动效率的CES生产函数引入中国八区域CGE模型,模拟区域间有偏技术进步、资本-劳动力替代弹性差异与区域政策效果之间的数量关系。结论为有偏技术进步、资本-劳动替代弹性对区域政策效果影响很大,西部、东北和中部地区投资需求增加对东南沿海、北部沿海、西南和京津经济增长有明显的带动作用;但是,对东北和中部经济增长没有明显带动作用。研究结论为“新东北现象”和“中部塌陷现象”产生的原因提出了一种新的解释思路。并提出使东北和中部地区的投资政策发挥更大作用,需要提高东北和中部地区资本-劳动替代弹性,从培育东北和中部地区经济增长的内生动力入手,鼓励东北和中部地区的创新活动,促进技术进步,进一步研究资本-劳动替代弹性的影响因素,促进东北和中部地区资本-劳动替代弹性提高的政策建议。
This paper theoretically analyzes the influence mechanism of regional biased technological progress and capital-labor substitution elasticity on regional policy effects. The CES production function including capital and labor efficiency was introduced into the CGE model of China’s eight regions to simulate the quantitative relationship between the biased technological progress and the elasticity of capital-labor substitution elasticity and the effect of regional policies. Conclusions For biased technological progress, the elasticity of capital-labor substitution has a great impact on the effectiveness of regional policies. The increased investment demand in the western, northeastern and central regions has obvious effects on the economic growth of the southeast coast, the northern coast, the southwest and Beijing and Tianjin. However, There is no obvious driving effect on the economic growth in Northeast and Central China. The conclusion of the study provides a new way of thinking for the causes of “the phenomenon of the” New Northeast China “and the” collapse phenomenon in the central region ". And proposed to make investment policies in the northeast and central regions play a greater role. We need to improve the elasticity of capital-labor substitution in northeastern and central regions. Starting with cultivating the endogenous driving forces of economic growth in the northeast and central regions, we should encourage innovation activities in the northeast and central regions, Promote technological progress, further study the factors that affect the elasticity of capital-labor substitution, and promote the policy suggestions on the elasticity of capital-labor substitution in the northeast and central regions.
